Linus Torvalds 4941a17751 Merge tag 'trace-ringbuffer-v6.18-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace 
Pull ring-buffer fix from Steven Rostedt:

 - Do not allow mmapped ring buffer to be split

   When the ring buffer VMA is split by a partial munmap or a MAP_FIXED,
   the kernel calls vm_ops->close() on each portion. This causes the
   ring_buffer_unmap() to be called multiple times. This causes
   subsequent calls to return -ENODEV and triggers a warning.

   There's no reason to allow user space to split up memory mapping of
   the ring buffer. Have it return -EINVAL when that happens.
